Application led August 5, 1919. Serial No. 575,635.

To all whom t may concern lBe it known that I, PATRICK F. MCCOR '-Maox, a citizen of the United States, and a resident of West Rutland, in-the county of Rutland and State of Vermont, have invented an improvement in Stoneworking-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

'lhis invention relates to stone working machines and more particularly to machines of the channeling type, the object of the present invention lbeing to provide a simple channelin apparatus intended more particularly t ough not exclusively for cutting the corner of a channel groove or that por tion which extends under an overlying side wall of a quarry.

Corner cutting has frequently beenl performed by pivotally mounting the tool standard of an ordinary track channeler upon the truck, and, with the truck fixed in position at the spot where the corner is to be cut, swinging the standard about its fixed pivotby means of the truck driving motor and by means of tool swinging mechanism especially provided for the purpose. This causes the cutting tools to cut along the arc of a circle and in so doing to reach in under the overhanging side Wall of the quarry.

ln the present embodiment of the invention, ll am enabled to dispense with much of the mechanism heretofore required by reciprocatively moving the tool support, as, for example, the truck, .while at the same ltime holding some part of the tool or tool support attached, to an extraneous object, such as the track, so that the reciprocatory `movement of the support causes the cutting devices to swing or move through a path reaching in under the quarry side wall.

The invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

lln the drawings; Figure 1 1s a plan view of a channeling machine embodying one form of--my invention; and lFig. 2 1s a front .elevation of the channeling machine shown in Fig. 1.

common form of driving mechanism is em-4 ployed, as follows: Connected to the crank shaft 5 of the engine is a beveled driving gear 6 meshing with the ears 7 and 8 loose upon the countershaft 9, ut adapted either one to be clutched thereto by the sliding leo clutch members 10 and 11 respectively. The

latter are moved simultaneously by the slide rod 12 and lever 12", so that either gear 7 or 8 may be clutched at will to drive the countershaft 9, and thereforev turn the latter in either direction. 1

The countershaft 9 carries the pinion 13 meshing with driving gear 14, the latter secured to the truck driving shaft 15 which drives the axles 16 and. wheels 2 through the worm gearing 17. By this mechanism the operator can drive the truck in either direction and reverse the same at will.

The machine illustrated is provided with the usual form of tool carrier or standard 18 mounted at the side of the truck, herein upon the standard carrying bracket 19, the latter being adapted to be adjustably ositioned and clamped at either end o the truck upon the trunnion bar 20.

Any form or construction of channeling tool and motor may be employed, but herein ll have illustrated a common form of air channeling engine 21 having rigidly secured thereto cross head guides 22, thetwo constituting a sliding frame adjustable lengthwise the standard through the medium of the feed screw 23. Any suitable means may be employed to turn the feed screw, but herein the upper end thereof is provided with; a beveled gear 24 meshing with a pinion 25, the latter carried at the end of the telescopic shaft 26. 'llhe lower end of the shaft is provided with apinion 27 meshing with beveled gear 28, the latter adapted to be clutched at will eitherl to the gear 29 or gear 30 by means of the sliding clutches 31 or 32. The gears-29 and/.30 respectively mesh with the gears 7 and 8. The feed screw 23 may be turned-in either direction or held at rest by shifting the clutches 31 and 32 to one posi-f tion or another. c The tool vfeed actuating mechanism forms no essential art` of my -invention and any ^form of tool ceding mechanism may be em. ployed, ora hand feed if desired may be utilized. v f .i

To the pistonfrod y33 of the engine 21 is secured the cross head 34 adapted to slide in' the cross headguides 22 and havin attached thereto the tool or tools 85 constitutin the channel gang. n. ne described formjof channeler may be employed in the usual. way in cutting'the ordinary channel groove. That is to say, the lstandard maybe clampedupright at either end of thetruck, asv represented l in dotted lines in Fig. 2,j one or more brace l '25 membersv 56 (also shown-(in dotted lines) being employed to' hold the standard rigid.

.v When it 1s desired tocut the corner, however, the brace member or members 56 are removed and the'. standard which has a pivotal'l connection 37' to the bracket 19 is loosened solas to befree toturn about such pivotal4 connection. The' truck is` then ar- V,ranged on the trackwaywith relation vto the walls of the'vv uarr in somesucli position as i is `represente by: otted lines ir'i Fig. 2, and

' there isjointed tosome partkof the tool carrier, Apreferably near the upperpart of the 'standard as at 38 a 39 brother suitable i' attachment memben the" opposite, end ,of

40l which has a jointed connection to'vsome iiXed 'extraneous object, such, for example, as the lclamp 40 xedly clamped to oneof the rails just back of. the truck. Theclamp 40 is easily detachable and'can vbe readily applied to a rail where desired when'corner cutting is to be done.:- Thepposition' in .which thev 'clamp is placed in' the' first, instance deter mines the throw .of `the cutting ytool and l standardandits adjustmenty .to a different "'position can be eiected 'anytime during a cutting operation to alter'the throw: I ,w c With the 'parts `arranged as shovvlivv in dotted lines Fig. 2, theltruck driving motor can' be thrown vinto coi'mection` with thetruck 'driving mechanism'by 'meansof the lever 13 to advanceI the truck,'just as in y Icha'nnelin groove;` vThe 'truclr'` then lnieves in tower thevhangingpywaly"Dicha f 6o quarry from. the dottedlme position' shown in Fig. 2 to' the' full.I line positionthere shown' carrying the pivotal su' port 37`of the stand- -ard afongwith itlffTeuppe'rfendofthe standard, however, being? attached to a, iixed '65 extraneous point; the w01 gang', win' swing toolsv for corner cuttin or move from the dotted line position shown to the full line position shown in Fig. 2, causing the cutting edges to describea path suitable for cutting the corner. When the inward extreme limit of movement has been reached, the truck driving mechanism can be reversed to swin the standard back to A the dotted line position shown, this cycle of Veliminating much complicated mechanism.

I By theterm corner cutting I comprehend notonly the cut under the overlying side wall of the quarry at the junction of the two side walls, but also the cut under such side Wall at any point thereof, the latter being y sometimes termed. transverse cutting. It is obvious that this application of the invention is but one of many and that it is applicable in the form herein shown or 1n modified forms thereof to many different, uses.

While I have lshown and described for purposes of illustration'one specific embodiment of the invention, it is to be understood 10o that the latter is not limited to the details herein shown nor to the application of the inventionk herein illustrated, nor to the spe- 'ciic form of machine to which the same is shown and applied, but that extensive devia- 4 ations may be made therefrom without departing from the spirit of the invention.
